Abstract
The invention concerns an electrostatic precipitator comprising an ionisation stage, a collector stage and a power supply. The power supply comprises a first high-voltage power supply unit for applying a first DC high voltage to the ionization stage and a second high-voltage power supply unit for applying a second DC high voltage to the collector stage. The first high-voltage power supply unit is configured to operate the ionization stage current-controlled. A current sensor required for this is advantageously arranged in the return line carrying low voltage, for which purpose the first high-voltage power supply unit and the second high-voltage power supply unit are galvanically isolated from the mains connection and from each other.

An electronic control system for a number of electrostatic precipitators of a building ventilation system, comprising at least one master device and a plurality of node devices, wherein
- each of the plurality of node devices is configured to be coupled to a corresponding electrostatic precipitator,
- the at least one master device and each node device having a computing unit,
- one or more chains of node devices can be connected to the at least one master device master device, wherein in each chain a first node device can be connected to the associated master device and the further node devices of the chain can each be connected to a predecessor node device, so that the node devices of the chain are connected to one another in series, the master device being the predecessor of the first node device of the connected chain or the predecessor of the first node devices of the connected chains, respectively,
- a position number is assigned to each of the node devices of a chain,
- the computing unit of the master device or the master devices, respectively, is configured, in a configuration mode, to cause the computing unit of the first node device of each connected chain to execute a configuration program that is configured:
- to receive the position number of its predecessor and to assign itself the position number increased by the value 1 and to store the position number in the node device,
- to determine whether a subsequent node device is connected and, if this is the case, to cause the computing unit of the subsequent node device to execute the configuration program.
